◎ Structural features
DAC458242 ABS bearings are angular contact ball bearings. Angular contact ball bearings can bear radial and axial loads. The contact angle affects the axial load capacity and the maximum speed. Generally speaking, the larger the contact angle, the stronger the axial load capacity, but the maximum speed will be reduced.
◎ Application areas
The wheel hub bearing is one of the key parts of the car. Its function is to support the wheel and ensure that the wheel can rotate smoothly. At the same time, it also needs to withstand the various forces from the vehicle's own weight, road bumps and braking. The bearing with ABS function also integrates the function of the wheel speed sensor, which can accurately measure the rotation speed of the wheel and transmit the signal to the vehicle's ABS system (anti-lock braking system), ESP system (electronic stability program), etc., so that these systems can accurately control and adjust according to the actual movement state of the wheel, improving the safety and stability of the vehicle.
◎ Installation and maintenance
Good lubrication can reduce the friction and wear of the bearing and increase the maximum speed of the bearing. For DAC458242 ABS bearings, the commonly used lubrication methods are grease lubrication and oil lubrication. If the viscosity of the grease is not appropriate, it will increase the friction of the bearing, cause the bearing to heat up, and limit the speed; oil lubrication has a better cooling effect, but if the oil supply is insufficient or the oil viscosity is not appropriate, it will also affect the speed of the bearing.
◎ Special Design
DAC458242 ABS bearings integrate sensors or signal generators of the ABS system. These additional components may increase the weight and rotational inertia of the bearings, and have a certain impact on the speed of the bearings. At the same time, in order to ensure the normal operation of the ABS system, the speed of the bearings also needs to be within a certain range to ensure that the sensors can accurately measure the speed of the wheels.
